When the hook is manually unhooked, the tail end of the hook tongue 6 can be manually pulled to overcome the pulling force generated by the return spring 8, so that the hook tongue 6 rotates clockwise along the hook tongue cavity 5, and when the straight surface of the hook tongue 6 is vertical to the connecting fine dried noodles 9, the two hooks are pulled to separate, so that the manual unhooking is completed.
When the automatic unhooking is carried out, the driving mechanism 7 can extend out to push the coupler knuckle 6 to overcome the tensile force generated by the return spring 8 and rotate clockwise along the outer circular surface of the coupler knuckle cavity 5, and when the straight surface of the coupler knuckle 6 is vertical to the connecting fine dried noodles 9, the two hooks are pulled to be separated, so that the automatic unhooking is completed.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
